Hello, this is the first time I'm writing a full guide here, but I've written a couple of achievement solutions posts. When I read a guide, I expect it to be thorough, make no assumptions about my skills or knowledge and be well formatted. With that in mind, I tried my best to write this. Hope it's useful!Sally's Salon Luxury Edition
Achievement Guide and Roadmap
by LanEvoIX

Introduction:
Sally's Salon Luxury edition is a fun and easy time management game. The goal is to manage customers and make them as happy as you can before you "cash" them. Click >>here<< for a review on WP Central for more details. It takes a while to complete the game since there are 75 levels you have to get a perfect grade on, each taking 10 to 15 minutes to finish.

You probably won't have any trouble getting 200, but it's possible to get in a sticky situation when it's very difficult to get a perfect grade on a level. Read on to know how to avoid this.

Abbreviated Walkthrough:Step 1. Knowing how it works and how to avoid a new playthrough.
Alright, let's grasp the game mechanics first, shall we?

Hearts - They show how satisfied you customer is with you. If they have 5 hearts when you "cash" them, that's a perfect rating for that customer, if they drop to zero hearts at any given moment, they just get up and leave. You have to avoid that if you want a perfect score!

Upgrades - Before every level you will have a chance to upgrade your salon. I recommend you go for coffee first (buy and upgrade), then candles where available, then new seats and assistants, and then upgrade everything. Since the game is easy, that's hardly a recipe you should follow strictly.

Coffee and magazines - Coffee gives an extra heart to a customer and it's a life saver, use it very often. Magazines slow down the speed in which customers get dissatisfied (lose hearts). Not critical, but very useful on 9th and 10th salons.

Candles - There are two types of candles, I call them Heart and Patience. Heart candles (red) will give every customer in the salon an extra heart. Patience candles (blue) will have the same effect as a magazine for a short time.

Types of customers - Now this is important. Some customers have less patience than others. I'm gonna list them in order of priority. I made up the names (except Elvis lookalike which I read someone saying, and it's perfect), but I don't think you'll have problem knowing which is which once you play the game.

Elvis lookalike - this is the most annoying one, and will lose hearts very quickly. He's your top priority

Executive lady - this is a high priority lady, she's not very patient, but is more than Elvis.

Brat girl - Kinda impatient young lady.

Brat guy - Not much of a problem maker, but not exactly patient.

Mister Dad - A regular man, looks life a father with his mustache.

Elderly lady - Very cool old lady, not much of a problem maker

Salon state (Open/Closed) - This was not clear to me at first, but you'll notice that on the top right corner of the screen there is a clock that eventually turns into a padlock. It shows you when the salon is open to receive new customers and when it's not. As soon as the padlock is there no customer will step inside anymore, and you'll just have to deal with the ones already in to finish the level. If the clock is still there new customers will just keep coming, as long as you have avaliable seats. So, the trick to get a high score (and the serve 20 customers in one level achievement) is to keep making available seats on the waiting area as fast as you possibly can. It's not hard at all to get the score needed to expert level, so don't sweat much over it.

Score/Grading system - There are three grades you can get, based on your score and customer satisfaction:

Daily goal reached - just earn whatever money the game indicates during the level (top of screen, right to Sally's picture).

Expert - reach the amount indicated in the same area after you've reached your daily goal

Perfect - reach the amount needed for Expert AND have all customers fully satisfied when you "cash" them out.

Avoid new playthrough - First of all, let me just say that WHEN STARTING you don't have to worry about this AT ALL on the first salon and second salon (caps for emphasis). You don't have many seats, so whatever the score you get, you'll be able to get a much higher one later. Start worrying about this when you salon if fully or near fully upgraded.

The whole problem centers around the concept that you can only get a better grade if you beat your previous score, meaning if the goal for Expert is 3,000 and you get 4,500 without full hearts (customers not completely satisfied), to be able to get a Perfect Rating now you need to top that 4,500 you got previously, not the original 3,000.

This can be a problem later in the game, because it's easier to get high score with Expert than it is to get with Perfect, and if you work real fast but let slip a non-completely satisfied customer, you'll have a very high score to beat with presumably more work to do (because now you need to make every customer satisfied while reaching more money). If you find yourself in a situation that you simply can't get a Perfect rating, you will have to erase your game and start over.

TLDR; So, to avoid this, I would suggest that once you have a good salon, and by that I mean all waiting area seats and the majority of the other seats bought, only finish a level with perfect rating. If by accident you "cash" a customer without full hearts, restart the level. It's not hard and will save you time in the long run.
